Got a warning Class XXX (From firebase) is implemented in both

I have sub project call FirebaseDependencies which include all of this for my app

However, when I try running the app with JitsiMeet, I got this warning

Seem like JitsiMeet also use Firebase,

Now, I don’t know how can I remove these warning, is this warning harmful?

Thanks
